ручное построение легенды с маркерами и строками

Я пытался сделать то же самое раньше, но у меня не получилось. В итоге я удалил некоторые элементы сюжета из легенды. Например:

h = plot(x,y); 
hasbehavior(h,'legend', false);

Вот еще один пример.

вот код, который я наконец придумал: он достаточно гибкий практически для любого приложения:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%     Legend Generator       %%%%%%%%%%%%%%%%%%%%%
%% NAME     : LEGEND_GENERATOR.m
%% FUNCTION : Generates a single plot for arbitrary legend 
%% INPUTS   : set of markers and related texts as cell and figure number
%% OUTPUTS  : No output
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%                      %%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%     AUG 28, 2012      %%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

function LEGEND_GENERATOR(Marker,text,Fignum,FONTSIZE,MARKERSIZE,LWD)

% clc;clear;close all;fclose all
% Marker = {'r -*' , 'b -o' , 'g --d'};
% text = {'First Fun ' , 'Second Fun ' , 'Third Fun ' };
% FONTSIZE = 6;
% Fignum = 26;

if length(Marker)~=length(text)
    error('You should have the same number of markers as texts');
end

%% FIGURE
set(0,'defaultaxesfontsize',FONTSIZE);
figure(Fignum);clf;hold on;set(gcf,'OuterPosition',[60  90 200  250],'PaperPositionMode','auto');


Leg_TEXTS = [];
for i = 1:length(Marker)
x = 0:0.1:2*pi;
y = 3*randn(1)*sin(x);
p = plot(x,y,Marker{i},'MarkerSize',MARKERSIZE,'LineWidth',LWD);
Leg_TEXTS = [ Leg_TEXTS ; {text{i}} ];
end


legend(Leg_TEXTS);
figure(Fignum);
set([gca;get(gca, 'children')], 'visible', 'off');

end

Вы всегда можете скрыть оси и все их дочерние элементы:

figure(1), clf, hold on

x = 0:0.1:2*pi;
y = sin(x);

p = plot(x,y);
legend('Sin(x)');

set([gca get(gca, 'children')], 'visible', 'off');
